Bothell's 36" of annual rainfall creates real conditions for moss and algae growth, especially on north-facing or shaded roof sections — algae-resistant shingles and more frequent inspections are worth considering here. The relatively narrow gap between average lows (45°F) and highs (60°F) in Bothell means less day-to-day thermal cycling stress on roofing materials than in climates with bigger swings. With average lows around 45°F in Bothell, occasional freeze-thaw cycling is possible in colder snaps, though it's not a dominant seasonal concern the way it is in harsher winter climates.
Bothell's temperature range doesn't impose the kind of seasonal sealing or safety constraints seen in more extreme climates, so roofing work can generally be scheduled with more flexibility here than in places with harsher winters or summers.
Algae-resistant architectural shingles or standing seam metal (metal typically lasting 40-70 years in Washington) tend to outperform standard 3-tab asphalt given Bothell's 36" of annual rainfall, since both shed water well and resist moss/algae growth better.
